IMPROVED CUTTER-STOCK FORIVIETAL-PLAN ERS.

Specifica-tion forming part of Letters Patent No. 15,379, dated July 22, 1856.

T0 @ZZ wir/0m t may concern:

Be it known that I, JOSHUA MASON, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Cutter Head or Stock for Metal-Planing Machines; and I do hereby declare that the following is'a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side view of my improvement, the frame or box in which the cutter head or stock is hung being bisected vertically. Fig. 2 is a front View ofthe same. Fig. 3 is a side View of the same, showing the manner in which the position of the cutter or tool is regulated.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in placing the 'cutter head or stock within a ring or band which is hung upon journals within a frame or box, so that the head or stock may swing or oscillate therein, and operating or adjusting the head or stock and regulating its position, as will be hereinafter fully shown and described, so that the cutter or tool may cut while the bed and work are moving in either direction, and also cut at different heights, according as its position is regulated.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it. f

A represents a frame or box, which is attached to a cross-bar of a metal planer so that it may slide thereon in the same way as the ordinary cutter or tool stocks in common use.

B isa ring or band which is suspended by journals a a within the frame or box A, and C is the cutter or tool stock, which is fitted within the ring orband Band prevented from turning therein by a set-screw b. The cutter or tool stock C is of cylindrical form, and the tool D is secured in its lower end by set-screws c, said screws passing horizontally into the stock. The tool D is double-edged-that is, it has a cuttingedge at its two opposite sides in the direction of" the movement of the bed on which the article to be planed is secured. The bed E is fitted in the machine and works -with a reciprocating motionin the usual manner.

F represents the stuff or work to be planed, which is placed on the bed 'To one of the journals a of the ring or band B there is attached a lever G, the lowerend vof which is connected to one end of a horiagainst which pinsfou the side of the bed E strike at the end of each stroke of the bed. 4 To the under side of the frame or box A there is attached a sliding plate L. This plate has an oblong slot g made through it., through which slot the toolD passes, and the plate L may be adjusted farther forward or backward by means of a screw h, arranged in any proper way.

The operation will be readily seen. As the bed E works or moves back and forth the cutter-stock C will be adjusted or swung in an inclined position in consequence of the pinsf striking against the spring e, and the .stock will be adj usted at the end of each stroke of the bed E, so that the proper inclination will be given the tool D. By this arrangement the tool Dwill cut while the bed is moving in either direction. .When the plate L is so lplaced that its slot g will be at equal distances, each side .of the tool D will have the saine inclination when moving in either direction, because the edges or ends of the slot g control the movement of the tool or limit the lengt-h of the vibrations or oscillations of the stock C; but when the plate L is so adjusted by turning the screwh as to throw the slot g one side of the tool D, so that one end of the slot will be fartherfrom the tool when in a vertical position than the opposite end, as shown in Fig. 3, the tool will be more inclined when the bed is moving in one direction than it will when the bed is moving in the opposite direction, and the cutting-edge of the tool will be-more elevated orat a greater' distance from its work the greater the inclination given the tool. By this means work or articles'to be planed having two different faces, one higher than the other, maybe planed at one operation or at the same time, the tool acting upon the lower surface of the work at one stroke or movement of the bed and upon theother or higher surface at the opposite movemen'J of the bed. The tool may also be tu rned obliquely to the Work by loosening the screw b and tu rnin e; the stock C within the ring or hemd B.

I am aware that double-edged tools have been previously used in metal-planers, so that the Work may be planed is the bed is moving in either direction. I therefore do not claim n, swinging or adjustable cutter-stock, irrespective of lbhe arrangement of the Same as herein shown and described; but

Vhat I do claim as new, and desire t0 secure by Letters Patent, is4

The cutter-stock C, pla-eed within a ring or lmnd B, which is suspended by journals .a within Lhe freine or box A, the stock being provided with n sliding or adjustable plate L, provided with a slot g, and the stock adj usted or operated atthe end of each stroke of the bed by the pinsff on the side of the bed and the levers G H I K, the above parts being a-rranged as' shown and described, for the puri pose specified.

JOSHUA MASON.
